Tritium is handled routinely at laboratories in the United States, Canada, Japan, and Europe. There are several applications for nondestructive assay of solid tritium-contaminated samples including environmental clean-up, routine assay of tritium handling equipment, assay of fuel elements used by fusion reactors including the proposed ITER reactor, and routine monitoring of fission reactor core m ...

Our goal is to develop an efficient technique for the production of high specific activity copper-6biomedical accelerators. Copper-64 (t 1/2 = 12.7 hr.) is an intermediate half-life positron emittingbeen shown to be a useful radiotracer for positron emission tomography (PET) as well as a promisingthe treatment of colorectal cancer. Copper-64 is currently reactor-produced and, because this radionpr ...

CHROMATIC ABERRATION LIMITS THE CURRENT DENSITY WHICH CAN BE PRODUCED BY FOCUSED ION BEAM SYSTEMS UTILIZING ELECTROSTATIC LENSES. STUDY OF SYSTEMS COMPRISING A LIQUID METAL FIELD IONIZATION SOURCE AND AN ACHROMATIC QUADRUPOLE LENS DOUBLET OFFERS THE PROSPECT OF OVERCOMING THIS LIMITATION. RESEARCH OBJECTIVES IN PHASE I INCLUDE IMPLEMENTATION OF METHODS TO COMPENSATE DEFECTS OTHER THAN CHROMATIC AB ...

A COMBINED THEORETIACL AND EXPERIMENTAL EFFORT IS PROPOSED FOR DEVELOPING A SUITABLE EPM MATERIAL WHICH PROVIDES SUBSTANTIAL PROTECTION AGAINST ANTICIPATED LASER THREATS. A NEW MATERIAL CONCEPT IS PROPOSED WHICH PROVIDES FOR DISSIPATION OF INCIDENT LASER ENERGY TO REFLECTION, ABLATION AND ANISOTROPIC THERMAL CONDUCTION. THIS MATERIAL IS EXPECTED TO INCREASE THE LASER INTERACTION TIME REQUIRED FOR ...

In this proposal, Quadrant Engineering seeks SBIR funds to investigate technologies leading to the development of a compact, low-cost multifunction radar system for use aboard an unmanned aerial vehicle (UAV). If successful, the proposed radar system will provide airborne early warning (AEW), ground mapping and ground motion-detection capabilities. Several novel antenna concepts will be in ...

40870 November 13, 1996 Science Research Laboratory, Inc. Several verification technologies for nuclear nonproliferation treaties use techniques that are based upon Prompt Neutron Activation (PNA) and neutron inelastic scattering. However, the use of neutrons is severely limited by the lack of an adequate electronic source. This project will develop a c ...

41161 Supercon, Inc. This project will investigate the possibility of developing a superconducting composite wire in a cost-effective way. It is expected that use of composite filaments instead of alloy filaments will greatly improve the fabricability of the superconducting wire and cut the production cost. In addition, substitution of regular bronze with high tin bronze can enhance the overall e ...

Demonstration of a cryogenically cooled electronic power converter/inverter exhibiting a throughput power of at least 50 kW is proposed. The demonstration topology may be utilized as a variable amplitude variable frequency dc-to-ac inverter, or as a polyphase ac-to-dc rectifier. Operation of the prototype is to be at a temperature of 77 degrees K utilizing liquid nitrogen as a coolan ...
